'Captain' of the Obake
(in story)
Sword: Gintsuki
When Gintsuki is in it's Hikidasu form it appears as the sword in the description pic
He is a master of Zanjutsu
Bala: able to fire a baseball sized 'bullet' of spiritual energy with high impact force that is also able to bust through a wall
Cero: is able to create a full strength, white Cero between his hands
Garganta: can create large tears in the space between the human world and Las Noches
Shimoyake: (frostbite) when in he or his sword are in the Release form anything they touch becomes frostbitten, if it is not living it becomes very cold and covered in a thick layer of frost, but if it is alive it is much worse
Kido List:
All Hado but no Bakudo
Gin Hikidasu: Haku was the unique ability to be able to change his sword from it's normal state into the Release state without changeing his own state, which saves energy, but makes it take longer to use normal Hikidasu
Weatherwise, Haku always causes the temperature around him to drop, sometimes enough for it to begin snowing
Haku was one of the last Obake to be created, and also one of the strongest. It is said that his design was based on Captain Hitsugaya. He was one of the most loyal Obake until he learned that their entire race was to be wiped out because of the mistake of one of them. Vowing to get revenge he escaped into Las Noches with a hand ful of his siblings by creating his first Garganta. Now he is strengthening his forces to get revenge on the Soul Society
